132 Study on the Flow Induced Structure of Liquid Crystalline Polymer Solution in a Two-Dimensional Channel with a Corner
Details
In this study, we have investigated the flow induced structure of liquid crystalline polymer solution in a flow through a two dimensional channel with a corner. The orientation angle and the dichroism were measured with a laser optical measurement system. The orientation angle had smoothly changed from the upstream of the corner to the downstream. A periodic oscillation in orientation angle was observed in the upstream flow, but it became smaller after the flow direction change. The dichroism also became a bit higher in the downstream region. In spite of no significant change in orientation angle and dichroism, a typical texture was obtained at the downstream region in polarized observation.
